To all whom it may-concern:

Be it known'that I, Fnsosmc E. W nona, a citizen of the United States, residing at Richmond Hill, Long Island, county ;of Queens, and State of New York, have 1nvented new and useful Improvements 1n Torches, of which the cation.

My invention relates to burners, blowipes or torches and is particularly useful in connection with meta fusin and cutting torches in which are em oyed some fuel gas such as acetylene, hy rogen, coal 3, etc., and some gas which su ports corn- Eiistion, such as oxygen. Torc es of this type are extensively used for the purpose of fusing two metal parts together or for cutting a metal apart. It is, however, to be understood that my invention is not ted to employment in t is connection since man features thereof are applicable to other km of burners and torches.

Among the generaltion are the provision kind above mentioned which is simple and chea in construction, emcient and economical in operation, and durable and safe in use.

My'invention will be fully understood and further objects thereof wil appear from consideration] of the embodiments ereof set forth in the following 7 ification and accompanying drawings, ta on together or searately.

n the drawings, Figure 1 is a plan view, partly in section, of a inning and cutting torch having my invention embodied therein: Fig. 1' ls-a sectionon the line 13-1 of 2 is a side elevation of the the torch, showing the man- 'usted t bjects of my invennozzle end of ner in which the nozzle can be ad aim in diflerent directionsrFi .8 is a plan view, in cross-section on an arg'edl'scale, of the nozzle end of the torch shown in Fig. 1: Fig 4 is a plan view partl in section, illustratin the nozzle. end 0 awelding torch bui t in accordance with my, invention: Fig. 6 is a sectional plan v; w of a welding and cutting torchccnstru ted in a rdancc with my invention, illustrating a odified arrangement for permittin the aim of the nozzle to be adg'usted; and ig. 6 shqws bushings with di erent vjsized holes theretiirough' adapted for use in the embodiments o my invention shown intbe other figures.

following is a speciflof a deviceof the of packing referred to throughout the several views by acters. v

' The torches illustrated in the drawings and hereinafter described are adapted for use with oxygen and acetylene.

Referring to Fig. 1, the handle portion of the torch is shown as comprising a lurality of conduits or pipes through which the oxygen and acetylene pass to the nozzle of the torch. The acetylene is furnished from a suitable source of sup ly through a hose connected to a pi e 10 w ich has interposed therein a control ing valve 11, and a cylin drical enlargement 12'which serves as a safety device to absolutely prevent the flame of the torch from working back into the acetylene feed hose should for any reason this hose become filled with a combustible mixture. The c linder 12 contains a fine mesh screen 18 ocated at the end toward the torch nozzle, and is filled with some rous material such, for exam is, as asbespacki coiled around itae f within the cylinder 1 as shown in Figs 1 and 1'. I have found that this kind and arrangement is particularly etlicacious, and I regard this kind of safety device as one of the new features of my invention. The oxygen supply hose (not shown) is conneoted to a common connection consisting of a two-way connection 15 which connects through two valves, 16 and 17, with conduits or pipes 18 and'19 which lead to the nozzle of the torch. The pipes 10, 18 and 19 may be connects to ether in any suitable way to form a han is or the torch, as by means of clips 20 and 91 through which said pipes pass.

The noszlecof the torch illustrated in Figs. 1, and a, comprises a body portion 25, which is mechanically connected to the pipes 10, 18 and 19 so as to be ad'ustable thereon to it variation in the irection of aim of the nozzle. The connections between the bodyportlon. 25 of the nozzle and the pipes forming the handle-are such that acetylene and oxyge can flow from the latter to passages in as cl body portion. These connections may he of any suitable form and as illustrated,;comprisejointed, pivotal unions between caps onthe ends of said pipes and perforated lu on the sides of sad body ortion 2!}. ferringtgoarticularly to Fig. the-union. between pipe 10 and the nozzlebcdy portion $5 comprises the cap so secured to the end of the pipe 10, a per cone-shaped cavity in s aid body portion, us

forated lug 31 projectin from said capat shown in Fig. 3. Th coneshaped end of right angles and rovi ed with a beveled, the tip is squared 01f" at such a point that a head, a perforated lug 32 projecting froin mixing chamber 61 is Qrmed in the cavity the body portion 25-, and a .nut 33 which between the bottom thei *of and the squared 70 screws upon the outside of the lug-32 and end ef'thetip, Iassinithrough the tip 60, has an internal-shoulder' which cooperates area passage 62 for t e combustiblemixwith a shoulder upon the lug 31 and thus ture, and a passage (53" for the oxygen jet serves-to draw the beveled head of the hi used when the torch is employed as a culm 31 into snug e agement with a seat 0111185 ting tool. The passage 62 extends from the in the end of t e lug 32. A tight joint, is outer end of the tip to the inner squared end thus provided between the pipe and the thereof, and tliiis communicates with the nomlej while at the same time pivotal move? mixing chamber 61-. It will be evident from ment ie permitted by slipping between the the drawing that the 'aeetylene passage 47 conical surfaces of the lugs 81 and 82, the is so arranged that it. opens'into the mixing nut Zia-bein looeenedi for this pu'r use if chamber- ()1 with which the ox ayon-passage necessary. he connectionbetween tiieipe' 45 also communicates througl the iole Hi 19 and the body'portion of the new e is the bushin 4.0.

This means comn-ises a removable 'bushin 49' which may e similar to that used in tiie nozzle of hi "5.

bushin 49' may screw into body portion 25- at the 'ottom of the cavity therein, and by having a number-of interchangeable bushings with different sized holes therein as shown in Fig. 6, the operator is-enabled to change the ell'ective size of -the oxy an assage where it. enters the mixing c am er. It will be obvious from an ins ection of Fig. 4 that oxygen assingthrou the oxygen passage 45" and the hole in he bushin 49 will-mix in the mixing chamber 61 wit the acetylene coming through :the passage 47-, and that the combustib a mixture Wll pass out through-the passa e 62* in the tip. t is, of course, to be unterstood that the method of changing the size of the oxygen passage just described, and shown in Fig. 4, is a p icable to the nozzle of the kind shown in 1g. 3; that is, if for an reason the needle valve of the previously ascribed nozzle should become in erative, the bushing 90 49 may ing diti'erent sized holes therein substituted, the needle of the needle valve being either removed or-screrwed back out of operative position.- In Fig. 5'is'.illustrated a form of nozzle, made in accordance with my invention, in which the body orti'o instead of being-pivoted on the con uits w portion'of'the torch, is ri w thereto." This 'form of=bo employed 'for torches where v ohange 'd-with reference y-portion maybe of :aim

Intfie torch oi-Fig. fr-the mouthpiece is of the same-form as-that shown in iFi .'-1 t.o 8, but imtmd-ofibeing-seomed direct y to thebody '5 portion at the noazle, it is connected therewith b'y a bent connection (5, at the form shown.

cavity in-the.body portion of .the nozzle. Two'passages ti2 and 68 extend through the connection 575 and are arranged as shown to cooperate with the passages in the mouthpiece 60, and .serve to connect the last named passages with the mixing chamber 61 and the oxygen passage 46*. Nuts 66 and 66 serve to secure the tip 60",tbe connection and the body ortion 25 together, in the same manner t at the nut 66 acts in the arrangement of Figs. 1 to 3. ,It is obvious that with the torch nozzle of Fi 5, using the bent connection 75, the aim o the nozzle may bead'usted by slightly loosening the nut-66 an rotating the connection '76 with relation to the nozzle body 25". Of course, the connection '75 may be made bentto any angle desired, that shown being merely illustrative.

lhe mode of o eration of the torches above described wi be understood by thos-- skilled in this art. In these torches, the size of-the flame is regulated by varying the effective size of the oxygen passage, either by means of the needle valve or b the use of bushin havin holes therein 0 different sizes; an by, at t ie-siime time, using a tip havin therein a particular diameter of passage or the combustible mixture. In other words, the size of the flame is controlled by regulating. the size of the oxygen passage leading to the mixing chamber and b regulating the diameter of the passage t irou h the ti for 'the combustible mixture. T ie size 0 the oxygen 'et of course depends upon the diameterof t e-oxygen passage inthe 'tip, said passage being made of-the proper size and of the -preer-di ameter with relation to the'diameter ofthppassage in that tip for the combustible m xture. With the forms ofnozzle before described, the mixing of -the .oxygen and acetylene in the mixing .ehamber is very'complete, robably owing to "the 'fact that the square end -of the tip -forming one'of the walls -of the mixing .cbamber is engaged-by the inflowingoxygen iand -,aeetylene with resultant vchurnin up .and mixture -of the'twoases. Wit or ran ments of thiB'kind, am enabled to use oxy en at. aunuch 'lower pressure than 'is ossi le with the torches now in use. witiout the occurrence of flashing back" or ignition of the mixture in the nozzle. In -fact,'1 am enabled by my invention to em- ;ploy oxygen and nest lene at substantially .equal pressures instea of being required to @use oxygen at .a much-higher pressure than the acetylene, as is'the present practice.

In the torches of 'Figs. 1 to 4 the aim of the'nozzle with reference to the handle por- 'tion maybe changed by moving said [107.710 on itsplvotal connections and with till noazle of Fig. ii the direction of aim may the varied by turning the connection 70,

with -a cone-shaped cavity similar -to the Ill! complished' with a single oxygen supply til:

with reference to the body portion as explained above. It is further to be noted that, with cutting torches built in accordahce with my invent on,

the-ox gen yet issues from the ,same tip as the ame; and that the position of the oxygenjet, with reference to the flame, can be adlusted as desired simply. b rotating the tip m the body portion 0ft e nozzle or in t e bent connection in which said tip is supported. This rotation of the tip is permitted b J the arrange. ment of the passages in the body portion or bent connection and 'n the tip and by the groove-in the conical'surfacecf the t1 as explained above. By my invention, t ereforc, not only is the nozzle of the torch adjustable as to direction of aim, but the relative loc'ationof the ox gen jet and the flame can also be regulate a cutting torch of this kind is, therefore, adapted for convenient useunder all conditions of service. -It is also to he noted that with the cutting torches above described,

ly hose is necessary,-this hose nected to the elbow 15 to which the pipes 18 and 19 are connected through valves and 17 which permit entirely independent regulation of the flow of oxy en in thetwo i I regard this independent regulation'of the oxygen cutting yet and the oxygen for the flame as high y desirable, an am not' aware that it has been before achose. y
